Find the value of x and y

Mathematics
1 answer:
allsm [11]3 years ago
8 0

We have the equations:

x + 3 = 15 and 3y - 1 = 2x - 4

x + 3 = 15    |-3

x = 12

Put the value of x to the second equation:

3y - 1 = 2(12) - 4

3y - 1 = 24 - 4

3y - 1 = 20     |+1

3y = 21    |:3

y = 7


<h3>Answer: x = 12 and y = 7.</h3>

What’s -1/6, 5/3, -5/6 in order from least to greatest
olga55 [171]

A negative number is always less than a positive number, so the only positive number, 5/3, is the greatest number of the three. -5/6 is less than -1/6, so the answer is:

-5/6, -1/6, 5/3

Which value of y below is the solution to the system shown below. A) y=6 B) y=-1 C) y=-4 D) y=8
Grace [21]

Answer:

D

Step-by-step explanation:

given the 2 equations

x + 2y = 27 → (1)

2x + 3y = 46 → (2)

Rearrange (1) expressing x in terms of y by subtracting 2y from both sides

x = 27 - 2y ← substitute into (2)

2(27 - 2y) + 3y = 46

54 - 4y + 3y = 46

54 - y = 46 ( subtract 54 from both sides )

- y = - 8 ( multiply both sides by - 1 )

y = 8 → D
